Curium is a transuranic radioactive chemical element with symbol Cm and atomic number 96. This element of the actinide series was named after Marie and Pierre Curie. A member of this group of elements, it is the lightest and most dense element that can be formed by neutron bombardment of lighter elements, but it is not the lightest element on the periodic table. Curium was first produced in July 1944 by the group of Glenn T.Seaborg from Berkeley, California, at the metallurgical laboratory of University of Chicago.
